Q: can you find the volume of the tank based on the opposite sides as the bases. 


This one was a tricky one lol. 

To find volume you need a formula: 

Formula for volume varies on the shape of the object.

<span><span>Cube = a 3<span>a is the side length

</span></span><span>Rectangular prism = a * b * c<span>a, b, c are the length, width, and height

</span></span><span>Cylinder = π * r 2 * h<span><span>r is the radius of the circular base</span><span>h is the height

for this one you would need the Rectangular prism formula. 

A: No you cannot find the volume because you need length, width, and height to figure out the volume of the rectangular prism. 

Hope this helped! :)
